This invention relates to certain improvements in hair waving devices in which a preformed tress of hair is subjected to the action of an exothermic material which, when moistened, will of itself generate heat suificient to impart a so-called-permanent wave to the tress.

This invention comprises a hair waving a device in which the hair tress is wound on. a

taining the liquid reagent being both inserted into the perforated tube in various positions with respect to each other and in various forms. V v Practical embodiments of my invention are represented in the accompanying drawin ,in which:

ig. 1 representsthe hair waving device in side elevation as in use;

Fig. 2 represents a longitudinal central section through the same, in which the cap- 1 sules containing the exothermic-material and Z5 to end within the perforated tube;

the liqu'idreagent therefor are inserted end Fig. 3 represents a similar view in which the capsule containing the exothermic material is of tubular form and-the capsule containing the liquid reagent is inserted within the exothermic material containing capsule; and

Fig. 4 represents a similar view in which the capsule containing the "liquid reagentisof tubular form and the capsule containing the, exothermic material is insertedwithin the reagent containing capsule.

The outer wrapper is denoted by 1, which wrapper may be made of any suitable non- ;absorbent material, such as parchment paper, foil, or the like. The clamp is denoted by 2,- which clamp may be of any Well known or approved form. It is to beunderstood that any suitable protective pad, not shown herein, may be inserted between the clamp 2 and the scalp of the person being treated.

' The perforated tube is denoted by 3, which tube may be of metal or other suitable 'stifi material.

In Fig.2 the capsule containing a suitable exothermic material 5, preferably in powdered form, is adapted to be inserted within the bore of the perforated tube 3. A capsule 6 containing a liquid reagent 7 for the exothermic material 5 is also inserted into the bore of the perforated tube 3, the capsules 4 and 6 beingarranged in-end to end relationship within the said perforated tube 3.

In Fi 3 the capsule 8 of tubular form is provide for containin the exothermic material 5, which capsule 1s inserted within the the tubular capsule 8.

In Fig. 4 the capsule 10 which contains the liquid reagent 7 is of tubular form and is inserted within the perforated tube 3. Thecapsule 11 which contains the exothermic material 5 is inserted within the tubular capsule 10.

In all .of the forms herein illustrated, the capsule containing the liquid rea eat is puncturable and the capsule containing the exothermic material may be either soluble or puncturable, as desired.

In practice, the tress of hair 12 is wrap ed aroundthe perforated tube 3 and secured in the usual manner. This tress may be moistened either before or after it is wound, by

-a suitable Waving solution, such for instance perforated tube 3. The capsule 9 which COD: tains the liquid reagent 7 is inserted within to close the same. When this has been done the exothermic action starts at once, where the. capsule containing the exothermic mate: rial is punctured, because of the application of moisture to the exothermic material by the release of the liquid reagent from the capsule containing said reagent. Where the capsule containing the exothermic material is soluble the liquid reagent first dissolves the capsule sufiiclently to gain access to the exothermic material.

Heat is thus set up Within the device sufficient to impart a so-called permanent wave to the pre-formed tress without requiring application of heat from an outside source.

It will be seen that the outside wrapper serves to confine the heat to a large extent within the device, the steam generated by the reaction of the liquid reagent with the exothermic material being permitted to escape through the crimped outer end of the said wrapper.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not intend to be limited to the particular embodiments herein shown and described, but

What I claim is:

1. A hair waving device comprising a perforated tube on which the hair tress is to be wound, a soluble capsule containing exothermic material and a puncturable capsule containing a liqiid reagent for the exothermic material, 0th inserted into the perforated tube. I

2. A hair waving device comprising a perforated tube on which the hair tress is to be wound, a puncturable capsule containing exothermic material and a puncturable capsule containing a liquid reagent for the exothermic material, both inserted into the perforated tube.

3. A hair waving device comprisin a perforated tube on which the hair tress 1s to be wound, a soluble capsule containing exothermic material and a puncturable capsule containing a liquid reagent for the exothermic material, both inserted end to end .Within the perforated tube.

4. A hair waving device comprising a perforated tube on which the hair tress is to be wound, a puncturable capsule containing exothermic material and, a puncturable capsule containing a liquid reagent for the exothermic material, both inserted end to end within the perforated tube.

5. A hair waving device comprising arforated tube on which the hair tress is to be wound, a tubular soluble capsule containing exothermic material, inserted into the perforated tube and a puncturable cap sule containing a liquid reagent for the exothermic material, inserted into the tubular capsule.

6. A hair waving device comprising a ed into the perforated tube and a puncturable capsule containing a liquid reagent for the exothermic material, inserted into the tubular capsule.

7. A hair waving device comprising a perforated tube on which the hair tress is to be wound, a soluble capsule containing exothermic material, inserted within the perforated tube and a tubular puncturable capsule containing a liquid reagent for the exothermic material, inserted between the perforated tube and the capsule containing the exothermic material.

8. A hair waving device comprising a perforated tube on which the hair tress is to be wound, a puncturable capsule containing exothermic material, inserted within the perforated tube and a tubular puncturable capsule containing a liquid reagent for the exothermic material, inserted between the perforated tube and the capsule containing the exothermic material.

9. A hair waving device includin a puncturable capsule containing a liqui reagent for exothermic material.

10. A hair waving device including a puncturable tubular capsule containing a liquid reagent for exothermic material.

In testimony, that Iclaim the foregoing as my invention, I have signed my name this 29th day of November, 1932.-
